Cervical Cancer Screening Guidelines

Pre-Procedure Preparation

Patients should empty their bladder before the procedure and be positioned in the dorsal lithotomy position to facilitate proper insertion and positioning of the speculum, as recommended by the American College of Obstetricians and Gynecologists and the Centers for Disease Control and Prevention 1
An appropriately sized speculum should be selected, which may be warmed with water, but lubricants should be avoided as they can interfere with cytology, according to the Centers for Disease Control and Prevention 1

The speculum should be gently inserted and adjusted to visualize the cervix, and if mucopurulent discharge is present, it should be carefully removed with a saline-soaked cotton swab before proceeding, as recommended by the Centers for Disease Control and Prevention 1
The extended tip spatula should be used first to sample the ectocervix, followed by the endocervical brush to sample the endocervical canal, according to the American College of Obstetricians and Gynecologists and the American Cancer Society 1, 2

The spatula should be rotated in a full 360-degree circle while maintaining contact with the cervix to ensure sampling of the transformation zone, as recommended by the American Society for Colposcopy and Cervical Pathology 1
The material from both devices should be immediately spread onto a properly labeled glass slide and fixed with spray fixative or by immersing in 95% ethanol for conventional Pap smears, according to the College of American Pathologists and the American Cancer Society 1, 2

HIV-positive women should receive cervical cytology screening twice within the first year after initial HIV diagnosis, and if both tests are normal, annual screening can be resumed, as recommended by the American College of Obstetricians and Gynecologists and the Centers for Disease Control and Prevention 1
Women who have had a hysterectomy do not require routine Pap tests unless the hysterectomy was performed due to cervical cancer or precursor lesions, according to the Centers for Disease Control and Prevention 1
Pregnant women should use a swab and Ayre's spatula, while cytobrushes are not recommended during pregnancy, as suggested by the Centers for Disease Control and Prevention 1
Anal Pap smears should target the anal canal epithelium and typically use a moistened Dacron swab or specialized anal brush, according to the American Cancer Society 2

The primary ICD-10 code to use for routine screening is Z12.4 (Encounter for screening for malignant neoplasm of cervix), as recommended by the American Academy of Family Physicians 3
For follow-up of previous abnormal Pap, the appropriate code to use is Z01.42 (Encounter for cervical smear to confirm findings of recent normal smear following initial abnormal smear) 3
For high-risk patients, the primary code to use is Z12.4, with appropriate risk factor codes as secondary, such as Z77.21 (Contact with and (suspected) exposure to potentially hazardous body fluids) or Z72.51-53 (High-risk sexual behavior) 3

Proper visualization of the cervix and use of appropriate collection devices are essential to prevent inadequate sampling of the transformation zone, as recommended by the American Society for Colposcopy and Cervical Pathology and the College of American Pathologists 1
Specimens should be fixed immediately to prevent air drying, which can distort cellular morphology, according to the College of American Pathologists and the American Cancer Society 1, 2
Mucopurulent discharge should be removed with a saline-soaked cotton swab before collection, and scheduling during menstruation should be avoided to prevent presence of blood or excessive mucus, as suggested by the Centers for Disease Control and Prevention 1

Patients should be warned about the possibility of light bleeding or spotting after the test, especially when using a cytobrush, and offered tampons or pads for any bleeding after the examination, as recommended by the American Academy of Pediatrics 4
Findings and recommendations should be discussed with the patient after she is dressed, according to the American Academy of Pediatrics 4
Pap test results, follow-up appointments, and results of follow-up appointments should be clearly documented in the clinic record, as recommended by the Centers for Disease Control and Prevention 1

Health-care providers who receive basic retraining on Pap test collection and clinics that use simple quality assurance measures are more likely to obtain satisfactory test results, according to the Centers for Disease Control and Prevention 1
Medicare covers Pap testing at three-year intervals, but allows yearly screening for women at high risk of cervical cancer, as recommended by the American Academy of Family Physicians 3
